Sangjo
During November 2025, Sangjo Kim expanded the DaleStudy/leetcode-study repository by implementing solutions for common algorithmic problems such as Contains Duplicate, Two Sum, Longest Consecutive Sequence, Top K Frequent Elements, and House Robber. Working exclusively in C++, Sangjo focused on algorithm design and data structures to create reusable, well-structured code that supports efficient problem-solving practice. He also standardized the codebase by aligning file naming conventions and ensuring consistent newline endings, which improved readability and maintainability. Through disciplined version control and clear commit documentation, Sangjo positioned the project for easier onboarding and future scalability, demonstrating strong attention to code quality.
